2008-02-20 04:12:02     question about porting u-boot-1.1.6 on BF531

I changed bf533-ezkit.h config as below:



#define BFIN_CPU                    ADSP_BF531


#define CONFIG_CLKIN_HZ          25000000

#define CONFIG_CLKIN_HALF               0

#define CONFIG_PLL_BYPASS               0

#define CONFIG_VCO_MULT   16         /*25MHz*16=400MHz*/

#define CONFIG_CCLK_DIV   2           /* 400M/2=200M   */

#define CONFIG_SCLK_DIV   4          /* 400M/4=100M   */


#define CONFIG_MEM_SIZE                           16                     /* 128, 64, 32, 16 */

#define CONFIG_MEM_ADD_WDTH              9                      /* 8, 9, 10, 11    */

#define CONFIG_MEM_MT48LC8M16A2TG_7E     1


After SPI booting, I found my SDRAM didn't work properly, but the CLKOUT and /CAS /RAS signals were OK except for CLKOUT's phase shifting 180 degree, then there's nothing output from serial port.


I found the u-boot.ldr file's 10-Byte section flag and address were mapped according to BF533, and in /cpu/bf533/start.S "copy DMA reset code to Hi of L1 SRAM" or others using "defBF533_extn.h" which defined L1_ISRAM, DATA_BANKA_SRAM according to BF533, too.


Need I change other source file, such as defBF533_extn.h???



Thank you so much.


Look forward to see you reply.


Best Regards,
